Efficient Recovery of Ilmenite from Vanadium Bearing Titanomagnetite in Panxi Area

Aiming to solve the problems of low recovery rate,high cost and smaller particle size of products in recovering ilmenite from tailings of a vanadium bearing titanomagnetite in Panxi area via conventional process of strong magnetic separation-strong magnetic separation-flotation,an efficient process that recover ilmenite from coarse and fine tailings of vanadium bearing titanomagnetite separately by procedures of strong magnetic separation-gravity separation-electric separation and strong magnetic separation-strong magnetic separation-flotation was investigated.The results show that the ilmenite concentrate with 47.40% of TiO₂ content and 61.84% of recovery rate can be obtained.Compared with the conventional process of strong magnetic separation-strong magnetic separation-flotation,the ilmenite recovery rate of the tailings by the proposed process increases by about 14 percentage points and the cost per unit ilmenite concentrate as well as the content of particles less than 0.074 mm is respectively decreased by 50 RMB and 20 percentage points.The obtained products are more suitable for preparation of titanium white pigment by sulphate process and production of acid-soluble high titanium slag.
